crash when rendering "allay"

Hello! I have a problem that is:

When I try to get past a point in my world, it crashes.
The game crashed whilst ticking entity
Error: java.lang.NullPointerException: Cannot invoke "dnm.a()" because "$$1" is null
Código de error: -1

I looked at the log file and it tells me that it is when it tries to render the entity "Allay"

attachment .txt

if it is not very well written, I want to use the translator because I am from Spain
